Have you taken a look at the system requirements of Adobe Photoshop CS6? It won't be straightforward to install it on an operating system it's not designed for. And there are tons of similar how-to-install-Photoshop questions on this site. So... what have you tried?

Use VirtualBox or something similar to actually create a virtual computer that you run Windows in.

Use Wine to run CreativeSuite. Wine is a way to run Windows software on Linux, but it's hit-or-miss.

Use CrossOvier to run CreativeSuite. CrossOver is based on Wine, but commercially supported. Unfortunately, it doesn't look like they have much in the way of CS6, though earlier versions might be better supported.

Bottom line is, you can't directly run CS6 on Linux. VirtualBox will probably be the most reliable method, but that isn't really using Linux; it's using Windows, inside Linux.
